but its dedicated to an appliance with a gfci service outlet already provided
Most of those devices require a GFCI by the manufacture instructions.
I am doing two wall hung boilers right now. The specs said a properly grounded outlet but nothing about a GFI. It did say you could remove the cord and hard wire with a switch if local codes required it. Interestingly it says a dedicated power supply is not required. This boiler (Navien) draws 5amps.
Yes, each one has two 2amp circulators, a system pump and a boiler pump. I think the boiler pump helps the other one along or something. One zone, just a t-stat and an outdoor sensor. It's the first one I did but it was easier then I thought it might be. Just bring the circulators and the low voltage into the control box and land them. More then one zone you would be wiring a zone panel also.Are these boilers for heating?
What you are describing here does not need to be cord connected. More than that I don't think the boilers or the gear that controls them comes with a plug in cord. Somebody added it I bet. Who? Not you I hope.Yes, each one has two 2amp circulators, a system pump and a boiler pump. I think the boiler pump helps the other one along or something. One zone, just a t-stat and an outdoor sensor.

Brand new and as I said the specs tell you you can remove the cord and direct wire.What you are describing here does not need to be cord connected. More than that I don't think the boilers or the gear that controls them comes with a plug in cord. Somebody added it I bet. Who? Not you I hope.
And when you were stating instructions you said where local codes require you may remove the cord and hardwire it. Seems 422.12 quoted by Jumper may help push the removing of the cord. If it is not used for central heating for some reason - then 422.12 doesn't apply.Brand new and as I said the specs tell you you can remove the cord and direct wire.
